When the Hardest Part Isn’t the Flight
When I was a junior officer, I thought the hardest part of a PCS (permanent change of station) to Japan was the packing. But as I watched shipmates and friends navigate the process with their families, I learned that one document—the Dependent Entry Approval (DEA)—can make or break your move. If you’re reading this because you’re worried about your overseas screening dependent status, especially after arriving in Japan without a DEA, you’re in the right place.
Before we dive in, let’s get one thing straight: this isn’t about scare tactics. It’s about keeping you from losing thousands of dollars and your sanity. I’ve seen it happen, and it’s entirely avoidable. The key is understanding the two separate but connected requirements: the overseas medical screening and the DEA.
Overseas Screening Dependent: Medical Conditions Are Usually Not the Problem
Many spouses worry that medical issues like type 2 diabetes, hypothyroidism, or high cholesterol will disqualify them from moving to Japan. In my experience, that’s rarely the case. The Navy’s overseas screening process is designed to ensure that dependents can receive adequate care at the new duty station. For well-managed conditions, Yokosuka’s naval hospital and local Japanese clinics are more than capable.
What the screening does require is a thorough review by your Primary Care Manager (PCM) and an approval stamp from the Overseas Screening Section (OSS). If your condition is stable and your paperwork is complete, you’ll likely get the green light. The real problem—the one that sinks families—is failing to complete the DEA before travel.

DEA: The Document You Cannot Skip
The Dependent Entry Approval is your family’s ticket to command sponsorship. Without it, you are not authorized to accompany your service member to Japan on the government’s dime. Arriving without a DEA, as the questioner did, is a serious administrative misstep. The command must now request a sponsorship letter to Commander, Fleet Activities Yokosuka (CFAY) to start the process retroactively. But here’s the kicker: without a DEA, you cannot get base housing or Overseas Housing Allowance (OHA), and those costs cannot be backdated.
I once had a shipmate whose wife and kids flew out on their own while he was on a detachment. They thought they could sort out the DEA later. Instead, they spent six weeks in a pricey hotel near Yokosuka, eating into their savings, while the command scrambled to get the paperwork approved. Don’t be that family.

What to Do If You Arrived Without a DEA
If you’re already in Japan without a DEA, you need to act fast. Here’s the sequence:
- Contact your command’s admin department immediately. They should be aware of the situation and ready to submit a command sponsorship letter to CFAY.
- Get your overseas screening documents in order. Even if your medical conditions are controlled, you need the signed screening form from your PCM.
- Work with the OSS at CFAY. They can guide you on the specific requirements for your dependent’s entry.
- Prepare for out-of-pocket expenses. Until the DEA is processed, you are responsible for housing and living costs. Keep all receipts—you may be able to claim some reimbursements later, but it’s not guaranteed.
The process can take weeks, so patience is key. But know that the command has an interest in getting you sponsored—they want their member focused on the mission, not on family logistics.
Financial and Housing Reality Check
Without a DEA and command sponsorship, you cannot move into Military Family Housing (MFH) or receive OHA. That means you’re on the private market, paying rent and utilities out of pocket. Once the DEA is approved, you can apply for retroactive OHA, but the approval is not automatic. Many families end up eating those costs.
The community response to the original question was clear: medical conditions like controlled diabetes are unlikely to disqualify you. The hang-up is the DEA. So if you’re preparing for a PCS to Japan, make sure you complete the overseas screening and DEA well before your travel date.

Final Word: Avoid the Disaster
Moving to Japan is an incredible adventure, but the administrative path is narrow. The best advice I can give any military spouse or family member is to treat the DEA like a golden ticket—don’t leave home without it. I’ve seen too many good families get tripped up by this one piece of paper. If you’re already in the thick of it, lean on your command and the OSS. And remember, you’re not alone: every service member who’s been through a Japan PCS has a story. Make yours one where you arrived prepared.
